On Travel-SE, there are currently 171 "Notable question" badges awarded. However, when one uses the search interface with views:2500, there are 106 results. The two numbers should be equal, and it's difficult to explain the difference with caching issues.

As the number of views is ever-increasing (as we all know, it's impossible to un-see things, unfortunately), this seems like a bug. Or perhaps I'm doing something wrong?

Also, some questions which should qualify don't appear on the search page. See this one, for example.

None of these questions are closed or deleted: views:2500 closed:yes and views:2500 deleted:yes return 0 results.

@Oded: we have 12 migrated questions total, none of which are even close

@Oded The example question above is shown in the badges page but not in the search page..

I would take a guess that the search is looking on a view count in different table and that view count wasn't updated for LONG time. Adding relevant tag in case I'm correct and it's bug in the search.
